"一吻定情" (It Started with a Kiss) is a Taiwanese romantic comedy television series that aired in 2019. It is an adaptation of the manga "Itazura na Kiss" by Kaoru Tada, also known as "Hana Yori Dango" or "Boys Over Flowers."

The Taiwanese version stars Jam Hsiao and Tiffany Hsu in the lead roles. However, you mentioned "柏原崇" (Shuji Kashiwabara), who is actually a Japanese actor famous for his role in the 1996 Japanese drama "Itazura na Kiss."

If you're looking for information specifically about the Taiwanese drama or Shuji Kashiwabara's role in the original Japanese drama, please let me know, and I can provide more detailed information.
